Hello everybody, not_anonymous here, first time poster long time visitor. I just couldn't pull myself back from discussing akward gantz facts with an interesting community so, here's my first go at it and I hope you appreciate it.
We all remember that mid schooler saying that gantzers are actually copies of their original selves right? When I first heard it I thought it was bull, and didnt pay attention to it. But as I kept reading through the manga I noticed those small little details that can turn your way of thinking upside down and when I finally realized it... I punched the wall...that kid was right.
How would I be so sure? Fortunately its not as hard to explain as it is to realize it on your own and, well, since you've eaten through this text so far I might as well give the details before I get my arse flamed for blabbering. Note that this goes far beyond the kei (titz) copy we all now, and far more shocking, hehe.
Every time a gantzer is teleported back to the room after their mission, they always appear in the position in which they have recieved their first lethal/mortal wound. For example in the first mission when katou chokes the veggiedad and gets his wrist cut open, when he is teleported back he appears in the same position, a second before he would've gotten injured.
Coincidence? Here are some other situations, i think with 2 more it will be enough:
1) Kurono teleports back from the "birdthing" mission aiming at the ceiling with his gun, why? because that was when the bird cleched his arm and inflicted kurono's first injury.
2) In the dojo mission kurono is recalled aiming at the floor with both guns in the gantz room, this is because a second later the 8 armed buddha thing chopped his leg and arm off.
The main point is Gantz teleports them a second before they recieve their first injury.
Wow this is getting interesting, isnt it? Maybe most of you already thought that the gantzers are copies of their original selves, after seeing that theres actually an original copy of kei (titz), but what you did not know and which is the most frustrating fact to realize is that the gantzers are recycled after every mission meaning that the other katous or kuronos die and are replaced with other unscratched bodies.
Then how do they remember how the mission ended if they're teleported before they get their first injury? Well I suppose it wouldnt be difficult for Gantz to make a backup copy of the gantzer's last memory into the new body.
I know most of you will think this is utter BS, may have derivations of this theory or are totally against it as a whole but as the old McDonald slogan goes: "Hey, it could happen".
